摘要

摘要对具有有利压力梯度的可压缩气体流动的传热参数进行了实验研究。采用瞬态传热方法确定了热传导系数和隔热（绝热）壁的温度。为了估计流动层流化的程度，将所获得的结果与已知的零压力梯度流动中板上形成的湍流边界层的相关系数进行了比较。针对所研究的超音速喷嘴配置，揭示了流动加速度对传热规律影响的一些规律性。

Experimental Study of the Heat Transfer at Compressible Gas Flow with a Favorable Pressure Gradient

Abstract

The parameters of heat transfer at compressible gas flow with a favorable pressure gradient have been experimentally studied. The heat transfer coefficients and the temperature of thermally insulated (adiabatic) wall are determined using the transient heat transfer method. To estimate the degree of flow laminarization, the results obtained are compared with the known dependences for the turbulent boundary layer developing on a plate in a zero-pressure gradient flow. Some regularities of the effect of flow acceleration on the heat transfer law are revealed for the studied configurations of supersonic nozzles.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
